The VK-A Series vibration transducer is an eddy-current transducer designed to satisfy the
American Petroleum Institute API St’d 670. It measures the shaft vibration of rotating
machinery without contact.
This is the most appropriate sensor to measure the shaft vibration of rotating machinery
supported by plain bearings and is frequently used to monitor the vibration of turbine
generators and compressors.
In addition, it can be used in an explosive gas atmosphere due to its intrinsic safety
construction.
